The pair of reinforcing installation positions are respectively constructed at two ends of the beam body and used for installing the reinforcing seats.

In some embodiments, the reinforcing installation position comprises an end flanging and a reinforcing rib, wherein the end flanging is configured at the end part of the beam body, so that the reinforcing installation position is more convenient to construct, and the connection strength between the end face of the longitudinal beam and the reinforcing seat is improved; the reinforcing rib is connected in the beam body to become the side of interval range in the tip turn-ups in towards the beam body, the reinforcing rib be used for with the tip turn-ups between reserve the space that forms reinforcement installation position. The reinforcing ribs are preferably connected to the inner sides of the flanges at the end parts in the direction towards the middle of the beam body, so that the reinforcing installation position structure forms a box-shaped structure positioned in the beam body, the bearing capacity of the end parts of the longitudinal beam is improved, and the connection strength between the longitudinal beam and the cross beam can be further improved by combining the arrangement of the reinforcing seat.

In some embodiments, the beam further includes a back panel, a top flap, and a number of stiffeners. The back plate is connected to one side of the air compressor hoisting plate in the width direction, the thickness of the beam body can be enlarged through the back plate, and the bearing capacity of the beam body is increased. The top turns over the board and constructs in the top of backplate to set up with air compressor machine hoist and mount board is relative, and the top turns over the board and can improve the connection area of contact between the roof beam body and the crossbeam, increases the bearing capacity of the roof beam body. Each strengthening rib becomes the interval range in the roof beam body, and the upper and lower both ends of every strengthening rib are respectively through turn-ups rigid coupling in the top turn over board and air compressor machine hoist and mount board, and the lateral part of strengthening rib passes through turn-ups rigid coupling in backplate. The reinforcing ribs play a role in reinforcing the beam body, so that the beam body has stronger structural strength in the length direction and the thickness direction.

In some embodiments, as shown in fig. 4, 6 and 7, both ends of a pair of stringers are connected to the first cross member 201 and the third cross member 203 through a reinforcement socket, respectively. The reinforcement seat is used for strengthening the connection strength between the longitudinal beam and the cross beam, improves the hanging bearing capacity and the safety of the air compressor hanging seat, and avoids the separation of the air compressor hanging seat and the cross beam. Specifically, the reinforcing seat includes a first reinforcing seat 111 and a second reinforcing seat 121, two ends of the first longitudinal beam 110 are connected to the first cross beam 201 and the third cross beam 203 through the first reinforcing seat 111, and two ends of the second longitudinal beam 120 are connected to the first cross beam 201 and the third cross beam 203 through the second reinforcing seat 121.

It can be understood that the first reinforcement seat 111 and the second reinforcement seat 121 have substantially the same structure. However, because the first longitudinal beam 110 and the second longitudinal beam 120 are installed at different positions on the cross beam, and a plurality of circular or oblong threading holes 2021 are distributed on the cross beam, as shown in fig. 8, considering that the overall structural strength of the cross beam should meet the requirement of the equipment hanging strength, and the threading holes 2021 should be avoided at the connection positions of the first longitudinal beam 110 and the second longitudinal beam 120 and the cross beam, the structures of the first reinforcing seat 111 and the second reinforcing seat 121 may be different based on the above structure.

The first reinforcing seat 111 and the second reinforcing seat 121 have the same structure: as shown in fig. 10 and 12, each of the first reinforcing seat 111 and the second reinforcing seat 121 includes a sloping plate, a fixed upright plate, and a pair of fixed side plates.

In the above structure, the reinforcing seat is preferably configured as a seat body structure having a certain thickness, so as to increase a welding area between the reinforcing seat and the longitudinal beam and further improve the connection strength.

In view of the above arrangement, the second reinforcing seat 121 further includes the reinforcing plate 122, because the mounting position of the second side member 120 may be located between the two threading holes 2021 in the cross member. As shown in fig. 13, the reinforcing plate 122 includes a first connecting edge 1221 and a second connecting edge 1222 connected at a predetermined angle, the first connecting edge 1221 is perpendicularly connected to the side of the cross member, and the second connecting edge 1222 is perpendicularly connected to the sloping plate. The first connecting edge 1221 is preferably connected between the adjacent threading holes 2021 of the cross beam, so as to avoid the connection strength of the connection part of the second reinforcement seat 121 and the cross beam from being reduced due to the arrangement of the threading holes 2021.

The two ends of the box body of the first longitudinal beam 110 are respectively surrounded by a first turning plate 115 and a first reinforcing rib 113 which are arranged at intervals and fixedly connected to the air compressor hoisting plate at the bottom to form a reinforcing installation position for installing the first reinforcing seat 111. A plurality of first reinforcing beads 112 are arranged at intervals in the box body of the first longitudinal beam 110.

As shown in fig. 10, the first reinforcing seat 111 specifically includes a first sloping plate 1111, a first fixed side plate 1112 integrally configured at two sides of the first sloping plate 1111, and a first fixed vertical plate 1113 located at the bottom end of the first sloping plate 1111. The top end of the first sloping plate 1111 and the end surfaces of the pair of first fixed side plates 1112 are welded to the outer side surface of the first cross beam 201 or the third cross beam 203; the bottom end of the first sloping plate 1111 is welded to the first turning plate 115 at the end of the first longitudinal beam 110 through the first fixed vertical plate 1113.

As shown in fig. 7 and 11, a second notch 126 is formed in the middle of the second longitudinal beam 120, the second notch 126 extends from the upper portion of the second back plate 127 to the top flap, and the width of the second notch 126 matches the thickness of the second cross beam 202, so that the second cross beam 202 can be inserted into the second notch 126 from top to bottom. The two ends of the box body of the second longitudinal beam 120 respectively surround a reinforcing installation position for installing the second reinforcing seat 121 by using a second turning plate 125 and a second reinforcing rib 124 which are arranged at intervals and fixedly connected to the air compressor hoisting plate at the bottom. A plurality of second reinforcing ribs 123 are arranged at intervals in the box body of the second longitudinal beam 120.

As shown in fig. 12, the second reinforcing seat 121 specifically includes a second inclined plate 1211, a second fixed side plate 1212 integrally configured on two sides of the second inclined plate 1211, and a second fixed vertical plate 1213 located at a bottom end of the second inclined plate 1211. The top end of the second inclined plate 1211 and the end surfaces of the pair of second fixed side plates 1212 are welded to the outer side surface of the first cross beam 201 or the third cross beam 203; the bottom end of the second sloping plate 1211 is welded to the second turning plate 125 at the end of the second longitudinal beam 120 through the second fixed vertical plate 1213.

As shown in fig. 13, the second reinforcing seat 121 further includes a reinforcing plate 122 connected between the second inclined plate 1211 and the cross member. The first connecting edge 1221 of the reinforcing plate 122 is perpendicularly connected to the outer side surface of the first cross member 201 or the third cross member 203, and the second connecting edge 1222 of the reinforcing plate 122 is perpendicularly connected to the second sloping plate 1211. The angle formed between the first connecting edge 1221 and the second connecting edge 1222 is the same as the angle formed between the second sloping plate 1211 and the outer side surface of the cross beam.

Understandably, in order to make the air compressor machine hang seat accord with the whole lightweight demand of rail vehicle, can only set up the strengthening rib in one side of the internal roof beam of longeron to the interval of adjacent strengthening rib is reduced to the opposite side in the roof beam body, so that the structure and the bearing capacity of the roof beam body obtain the equilibrium, in other words, utilize the strengthening rib both to play the reinforcement effect to the roof beam body of strengthening rib, can also realize the reinforcement effect to reinforcement installation position, thereby save a strengthening rib in the roof beam body. For example, as shown in fig. 9 and 11, the first reinforcing rib 113 of the first longitudinal beam 110 is disposed on the side of the beam body of the first longitudinal beam 110 close to the first cross beam 201, and correspondingly, the second reinforcing rib 124 of the second longitudinal beam 120 is disposed on the side of the beam body of the second longitudinal beam 120 close to the third cross beam 203. It can be understood that the positions of the first reinforcing rib 113 and the second reinforcing rib 124 can be changed, and only the bearing capacity and the structural balance inside the beam body of the first longitudinal beam 110 and the second longitudinal beam 120 need to be satisfied, and the whole structure and the bearing capacity of the air compressor hanger can be balanced.

It can be understood that, based on the structural arrangement of the first cross member 201 and the third cross member 203 and the difference in the installation positions of the first longitudinal member 110 and the second longitudinal member 120 on the respective cross members, it is preferable that the first back plate 116 of the first longitudinal member 110 is configured as a plate body structure vertically arranged with respect to the bottom surface of the cross members, that is, the beam body cross section of the first longitudinal member 110 is configured as an equal-section structure. The second back plate 127 of the second longitudinal beam 120 is configured as a variable section plate body structure which is arranged in a curved surface structure relative to the bottom surface of the cross beam, namely, the beam body cross section of the second longitudinal beam 120 is configured as a variable section special-shaped structure.

It can be understood that, based on the structural arrangement of the first cross beam 201 and the third cross beam 203 and the difference between the installation positions of the first longitudinal beam 110 and the second longitudinal beam 120 on the respective cross beams, the inclination of the first inclined plate 1111 of the first reinforcement seat 111 is steeper than the inclination of the second inclined plate 1211 of the second reinforcement seat 121, and in order to consider that the distance between the threading holes 2021 on the cross beams is small, the second reinforcement seat 121 needs to connect the reinforcement plate 122 between the second inclined plate 1211 and the outer side surface of the cross beam, so the second inclined plate 1211 with a gentle gradient is constructed to install the reinforcement plate 122, and the structural strength of the second reinforcement seat 121 is improved.

Understandably, all structures of air compressor machine hanging seat described in the embodiment of the present invention are preferably made of austenitic stainless steel material, so as to further improve the structural strength.
